The tandem application of CO2 electrolysis with syngas fermentation holds promise for achieving heightened production rates and improved product quality. However, the significant impact composition on mixed culture-based microbial chain elongation remains unclear. Additionally, effective methods generating an adjustable from acidic are currently lacking. This study successfully demonstrated medium-chain fatty acids through fermentation. CO could serve as sole energy source or electron donor (when cofed acetate) caproate generation. Furthermore, results gas diffusion electrode structure engineering highlighted that use carbon black, either alone in combination graphite, enabled consistent generation (pH 1). black layer significantly selectivity, increasing 0% to 43.5% (0.05 M K+) further 92.4% (0.5 K+). enhancement performance was attributed promotion K+ accumulation, stabilizing catalytically active sites, rather than creating a localized alkaline environment CO2-to-CO conversion. research contributes advancement hybrid technology sustainable reduction chemical production.
